| 摘 要： | 提出一种基于电动汽车变速均匀性控制的加速度模型,在对永磁同步电动机驱动系统分析的基础上,建立系统单变量CARIMA模型,采用递推最小二乘法对模型参数进行辨识;并设计速度预测PI控制器,以柔化加速度变动带来的冲击。最后对电动汽车的变速过程进行仿真,仿真结果表明:该方法能够实现对电动汽车纵向加速度的有效控制且鲁棒性强。

| Abstract: | An acceleration model for electric vehicle is presented.Based on the analysis on the drive system of the permanent magnet synchronous motor,a single-variable CARIMA model is established and the parameters of the model are identified by recursive least squares method.A generalized predictive PI controller is designed and adopted to soften the impact caused by the abrupt change of acceleration.At last,the starting and speed variation process of the electric vehicle are simulated.The results show that the scheme can realize the effective control of the longitudinal acceleration of the vehicle. |
